and
(f+g)(x) =
combining like terms gives you answer choice B
Final amount = 6675, interest earned will be 675
Step-by-step explanation:
1)X represents the time he spent in cardio.
Y represents the time he spent in weighted.
2)If you could put the options on the second one it would be better.
3)4x+y=210
3x+2y=195
y=210-4x
3x+2(210-4x)=195
3x+420-8x=195
5x=420-195
5x=225
x=45
y=30
Total time of one cardi and weighted = 75min= 5/4 h.
4)2x+4y=
90+120=210 total time of week three.
X<9
The answer is x<9 because you first subtract 4 from both sides then divide both sides by -3. Which then would give you 9.
